Sure it’s fine. Post what you want (within obvious limits of decency and so on.)
My personal reaction? I just do not use the word “ideology” the way these guys do. They use it in the mainstream way where it means any consciously held political doctrine. To me that barely scratches the surface, if it even reaches the surface enough to scratch it at all.
To me ideology is largely unconscious norms, values, and beliefs that have the effect of defending and justifying (OR opposing) an established system of social power.
So why didn’t most medieval peasants rebel? Because they believed god arranged the world into strict social hierarchies and that sedition was also sin.
